The internode messages are custom binary format. In the code it's in the o.a.c.net package, the Message class is the thing sent around. MessageService is the main guy handling incoming and outgoing messages.
The node listens on the storage_port and listen_address as set in conf/cassandra.yaml Hope that helps.
